How difficult it was for these churchmen to carry out their policy of religion without letters may be best observed by viewing the conditions then obtaining. In most Southern States in which Negro preachers could not be deterred from their mission by public sentiment, they were prohibited by law from exhorting their fellows. The ground for such action was usually said to be incompetency and liability to abuse their office and influence to the injury of the laws and peace of the country. The elimination of the Christian teachers of the Negro race, and the prevention of the immigration of workers from the Northern States rendered the blacks helpless and dependent upon a few benevolent white ministers of the slave communities. During this period of unusual proselyting among the whites, these preachers could not minister to the needs of their own race.[1] Besides, even when there was found a white clergyman who was willing to labor among these lowly people, he often knew little about the inner workings of their minds, and failing to enlighten their understanding, left them the victims of sinful habits, incident to the institution of slavery. [Footnote 1: Jones, _Religious Instruction_, p. 175.] To a civilized man the result was alarming. The Church as an institution had ceased to be the means by which the Negroes of the South could be enlightened. The Sabbath-schools in which so many colored people there had learned to read and write had by 1834 restricted their work to oral instruction.[1] In places where the blacks once had the privilege of getting an elementary education, only an inconceivable fraction of them could rise above illiteracy. Most of these were freedmen found in towns and cities. With the exception of a few slaves who were allowed the benefits of religious instruction, these despised beings were generally neglected and left to die like heathen. In 1840 there were in the South only fifteen colored Sabbath-schools, with an attendance of about 1459. [Footnote 1: Goodell, _Slave Code_, p. 324.]
